Interaction of a two-level XY n-spin model with a cavity field

A simplified version of the XY n-spin cyclic model interacting with a single-mode cavity field in the rotating-wave approximation is investigated in the framework of a two-level system. Computation of the energy of the spin system follows from an appropriate tracing of the analytic propagator path i...
